KVM: s390: interpretive execution of SIGP EXTERNAL CALL

2014-05-16T12:57:28+00:00

If the sigp interpretation facility is installed, most SIGP EXTERNAL CALL operations will be interpreted instead of intercepted. A partial execution interception will occurr at the sending cpu only if the target cpu is in the wait state ("W" bit in the cpuflags set). Instruction interception will only happen in error cases (e.g. cpu addr invalid). As a sending cpu might set the external call interrupt pending flags at the target cpu at every point in time, we can't handle this kind of interrupt using our kvm interrupt injection mechanism. The injection will be done automatically by the SIE when preparing the start of the target cpu.

KVM: s390: Use intercept_insn decoder in trace event

2014-05-16T12:57:27+00:00

The current trace definition doesn't work very well with the perf tool. Perf shows a "insn_to_mnemonic not found" message. Let's handle the decoding completely in a parseable format.

KVM: s390: Don't enable skeys by default

2014-04-22T07:36:26+00:00

The first invocation of storage key operations on a given cpu will be intercepted. On these intercepts we will enable storage keys for the guest and remove the previously added intercepts. Signed-off-by: Dominik Dingel Acked-by: Martin Schwidefsky Signed-off-by: Christian Borntraeger

KVM: async_pf: Async page fault support on s390

2014-01-30T12:11:02+00:00

This patch enables async page faults for s390 kvm guests. It provides the userspace API to enable and disable_wait this feature. The disable_wait will enforce that the feature is off by waiting on it. Also it includes the diagnose code, called by the guest to enable async page faults. The async page faults will use an already existing guest interface for this purpose, as described in "CP Programming Services (SC24-6084)".
